Expand description

Audio and video codec implementations for OxiMedia.

This crate provides encoding and decoding for royalty-free codecs:

§Video Codecs

  • AV1 - Alliance for Open Media codec (primary)
  • VP9 - Google’s royalty-free codec
  • VP8 - Google’s earlier royalty-free codec
  • Theora - Xiph.Org Foundation codec (VP3-based)

§Audio Codecs

  • Opus - Modern low-latency audio codec

§Architecture

All codecs implement unified traits:

§Example

ⓘ
use oximedia_codec::{VideoDecoder, Av1Decoder};

let mut decoder = Av1Decoder::new(&codec_params)?;
decoder.send_packet(&packet)?;
while let Some(frame) = decoder.receive_frame()? {
    // Process decoded frame
}

§Audio Example

ⓘ
use oximedia_codec::opus::OpusDecoder;

let mut decoder = OpusDecoder::new(48000, 2)?;
let audio_frame = decoder.decode_packet(&packet_data)?;
